What size are our valves?

[Jimme T]

im trying to find out what the stock size of our intake and exhaust valves are. Specifically for a 2008 speed 3. When I search it everything I find just says Oem size or +1mm. I’m also trying to find what angles our seats are cut.

Guessing 33.5 and 28.3 ish or thereabouts.
